Not sure how common this knowledge is, but I thought I'd share.
Starting with the bad news, just to get it out of the way: the premiere of season two has been delayed till some currently-undetermined time next year
This is based on online reports about the Marvel Television panel at NYCC and some comments by creative staff Christopher Yost
(story editor) and Josh Fine
(supervising producer). Whether that means it'll start around the time as the upcoming Ultimate Spider-Man cartoon series like these sources
(same person at different sites) have suggested – or if we’ll have to wait till around the time the live-action Avengers movie is released (if the two aren't around the same time anyway!) – is unknown at the moment.
But there's good news too!
We now have a much clearer idea of the guest stars and the storyline(s) that the new season will bring. Here’s a rundown of what we can expect, starting with generalities and moving on to specifics.
To start with, two videos that have been around for a while (so you may have seen them before) - interviews with Yost and Fine.
The first has ( the two of them speaking generally about some of season two's storylines )
And the second ( has them talking about talking about the second season’s new heroes - and the new looks for some of the older ones. )
And finally, here’s ( an official trailer for the second season and a link to a gallery of screen caps from said trailer )
Additionally, the first episode of the new season has now (apparently) been seen twice at panels at SDCC as well as the panel at NYCC, so now we have a clearer idea of what that is going to be about. ( Here's a general description (with links to more spoilery ones) and one picture (a series of screencaps put together, I think). )
So looking forward to this, even if it'll be only next year when I see it.( For legality, some pages (not all related) from the four-issue tie-in comic. )
